Introduction Multi-echo imaging has previously been used for fat/water separation and fat quantification [1,2]. The same technique may potentially also be able to differentiate different fat types depending on the amount of unsaturated fatty acids. The fatty acid composition of adipose tissue is not only dependent on the diet, but may also be interesting in e.g. chronic inflammations [3]. Also,...

background: the heterogeneous composition of the human body presents numerous tissue types and cavities with widely differing radiologic properties. the aim of the present work was to develop a low cost homogeneous and heterogeneous phantom and the absorbed dose were measured by ionization chamber for different radiotherapy treatment techniques and compared with treatment planning system absorb...

background long-term clinical symptoms and functional status of above-knee amputees are not well documented. this study documents the long-term outcomes of war related above-knee amputations. objective to study the long-term outcomes of unilateral above-knee amputation. materials and methods the study consisted of a comprehensive assessment, examination, and review of history and wartime medica...

PURPOSE To determine whether high signal-to-noise ratio (SNR) acquisitions improve the repeatability of liver proton density fat fraction (PDFF) measurements using confounder-corrected chemical shift-encoded magnetic resonance (MR) imaging (CSE-MRI). MATERIALS AND METHODS Eleven fat-water phantoms were scanned with 8 different protocols with varying SNR. After repositioning the phantoms, the ...

introduction based on task group no. 43 (tg-43u1) recommendations, water phantom is proposed as a reference phantom for the dosimetry of brachytherapy sources. the experimental determination of tg-43 parameters is usually performed in water-equivalent solid phantoms. the purpose of this study was to determine the conversion factors for equalizing solid phantoms to water. materials and methods t...

A dual-band wearable antenna is designed on a textile material. The design operates at ISM bands available for Wireless Body Area Network and Local with an input match better than -15 dB. by using Computational Electromagnetic Software (CEMS) based finite-difference time-domain (FDTD) method. three-layer phantom model including skin, fat muscle has been considered to compute the specific absorp...

This Letter introduces a feasibility study of a scanning system for applications in biomedical bone imaging operating in the microwave range 0.5-4 GHz. Mechanical uncertainties and data acquisition time are minimised by using a fully automated scanner that controls two antipodal Vivaldi antennas. Accurate antenna positioning and synchronisation with data acquisition enables a rigorous proof-of-...

BACKGROUND Imaging studies of bones in patients with sensory deficits are scarce. AIM To investigate bone MR images of the lower limb in diabetic patients with severe sensory polyneuropathy, and in control subjects without sensory deficits. METHODS Routine T1 weighted and T2-fat-suppressed-STIR-sequences without contrast media were performed of the asymptomatic foot in 10 diabetic patients ...

In both photoacoustic (PA) and ultrasonic (US) imaging, overall image quality is influenced by the optical and acoustical properties of the medium. Consequently, with the increased use of combined PA and US (PAUS) imaging in preclinical and clinical applications, the ability to provide phantoms that are capable of mimicking desired properties of soft tissues is critical. To this end, gelatin-ba...
